Mr. Chen, regarding your inquiry, first of all, let's talk about the parts of the timing belt. Your car should have been changed a long time ago. It is recommended that you go to the 4s shop in time to replace the timing belt components, including the belt, tensioner and idler, and check the water pump when replacing the belt. Regarding carbon deposition, the throttle body is cleaned every 65,438+05,000 km, and the fuel injector, air inlet and three-way catalyst are cleaned every year or every 30,000 km. Vehicles driving in urban areas with low gears and low speeds for a long time are prone to carbon deposition, and excessive carbon deposition will lead to decreased power and increased fuel consumption. If the vehicle runs at a high speed for a long time, the maintenance interval can be appropriately extended, and the electronic throttle valve should be cleaned every 20,000 kilometers, and the intake port, injector and three-way catalyst should be cleaned every 50,000 kilometers.
